[Epidemiology of peptic ulcer at the "Salvador Zubirán" National Institute of Nutrition].
In order to know the variations on the epidemiology of peptic ulcer in the INNSZ we have studied 850 patients with peptic ulcer between January 1980 and July 1988, in comparison with 1,000 patients studied in 1960 and in a similar group in 1980. In the 1988 group, we analyze the characteristics such as: sex, age, localization of the ulcer, occupation and habits and we compare them with a control group of 850 patients studied in the same time in the INNSZ. According with these results, we can appreciate that the duodenal ulcer (DU) has decreased from 77.5% in 1960 to 57.5% in 1988. The difference is statistic significant (p less than 0.005). About gastric ulcer (GU), its frequency has been increased from 17.6% to 29.6% with a statistic significant difference (p less than 0.005). The esophageal ulcers has been increased too. Other observation is that the general proportion of ulcers in the hospital population has been decreased from 7% in 1960 to 3.6% in 1988.
